  • Récupération d’informations sur le site maître à l’installation d’une instance

    26 novembre 2010, par

    Utilité
    Sur le site principal, une instance de mutualisation est définie par plusieurs choses : Les données dans la table spip_mutus ; Son logo ; Son auteur principal (id_admin dans la table spip_mutus correspondant à un id_auteur de la table spip_auteurs)qui sera le seul à pouvoir créer définitivement l’instance de mutualisation ;
    Il peut donc être tout à fait judicieux de vouloir récupérer certaines de ces informations afin de compléter l’installation d’une instance pour, par exemple : récupérer le (...)

  • Possibilité de déploiement en ferme

    12 avril 2011, par

    MediaSPIP peut être installé comme une ferme, avec un seul "noyau" hébergé sur un serveur dédié et utilisé par une multitude de sites différents.
    Cela permet, par exemple : de pouvoir partager les frais de mise en œuvre entre plusieurs projets / individus ; de pouvoir déployer rapidement une multitude de sites uniques ; d’éviter d’avoir à mettre l’ensemble des créations dans un fourre-tout numérique comme c’est le cas pour les grandes plate-formes tout public disséminées sur le (...)

  • ffmpeg stops randomly with "No more output streams to write to, finishing" when reading rtsp stream [on hold]

    7 juin 2016, par ImagineDragon

    Basically I am running the following ffmpeg command to read an h264 rtsp stream using hls muxer, under Ubuntu 14.04 64bit with i7 CPU and 8GB memory :

    The problem is that ffmpeg exits randomly after 5 to 20 minutes. The RTSP is a live stream so stopping every 5 minute is really not acceptable. In the ffmpeg log I can’t see any noticeable error except "No more output streams to write to, finishing." near the end. Can someone shed some light upon this ? How can I make ffmpeg run without stopping ? Thanks

  • Streaming H.264 over UDP using FFmpeg, and "dimensions not set" error

    3 septembre 2015, par Baris Demiray

    I’m trying to stream H.264 over UDP with no luck so far. Here is a minimal code that you can reproduce the problem.

    To compile,

    g++ -o test -lavcodec -lavformat -lavutil test.cpp

    For those who has even more time to spare on my problem, when I change m_output to rtsp://127.0.0.1:8554/live.sdp, and ffplay command to ffplay -rtsp_flags listen -i rtsp://127.0.0.1:8554/live.sdp I get the error,

    [libx264 @ 0x1e056c0] using mv_range_thread = 24

       Stream #0:0, 0, 0/0: Video: h264 (libx264), -1 reference frame, none, q=-1--1
    Cannot open output: Protocol not found

    Am I naive to expect that streaming protocol will be changed like this ?

  • Set protocol-level metadata in AVFormatContext any time a packet is read.

    Set protocol-level metadata in AVFormatContext any time a packet is read.
    

    If any option named "metadata" is set inside the context, it is pulled up to
    the context and then the option is cleared.
